A human-controlled country that is an elector in the Holy Roman Empire is now unable to vote for itself (this means that the player is restricted in the same way that AI-controlled countries are restricted). The player will automatically vote for the country that it would vote for if it were controlled by the AI (reputation being the primary determining factor, with ties being broken by other considerations such as prestige, size, strength, reputation, etc.).
Being the Papal Controller now also helps to improve your countryÃ¢â‚¬â„¢s reputation.
The rate that maps will spread to other countries has undergone a large adjustment. A newly-discovered province will not become known to other countries for at least 50 years (unless they discover it independently).
